To all whom, it may concern:

Be it known that I, ERASTUS E. WINKLEY, a citizen of the United States, residing at Lynn, in the county of Essexland Stateof Massachusetts, have invented certain new and useful Improvements in Automatic Sewing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to automatic machines in which the requisite relative movements between the work and means for operating thereon are automatically controlled and effected to maintain the work andop crating means in proper relation as the point of operation progresses along the work.

In welt and turn sewing machines, outsole stitchers, rounding and channeling machines, and various other shoe machines, it is necessary during the feed of the shoe to change the angular relation of the operating means and work by relatively tipping said means and the shoe both transversely and longitudinally of the line of feed to maintain the operating means and shoe in proper relation at the point of operation. In an application filed May 25, 1916, Serial No. 99,751, amachine is shown and described in which the relativetransverse and longitudinal tipping movements are controlled by feelers acting adjacent to the path of travel at the point of operation along the work. is determined throughout. the operation along the work by the contour of the work engaged by the controlling feeler.

In doing certain classes of work, it is desirable or important that an additional relative tip between V the operating means and the work not indicated by a change in the contour of the work, be secured at certain points in the travel of the point of operation. For instance, in sewing the inseam of a welt or turn shoe the shoe or sewing mechanism should bev tipped transversely when sewing about the toe (and in some cases when sewing through the shank) to a greater degree than is indicated by the change in the contour-of the sole adjacent In this machine the transverse v tip to the channel. It is accordingly the pri- ERASTUS E. WINKLEY, 0F LYNN, MASSACHUSETTS, ASSIGNOR, BY MESNE ASSIGN- mary object of the present invention to prov1de means for securing the above result. To th1s end the invention contemplates the provision in a machine in which a feeler acting along a contour of the work acts to vary the angular relation between thework and operatmg means in accordance with said contour of means for effecting a, change in said angular relation not indicated by the feeler. 'In embodyingthe invention in an mseam sewlng machine such as shown in the above application, to secure an additional or abnormal lateral tip when operating about the toe or when operating about the toe and through the shank, it is pre ferred to effect the required change in the angular relation of the sewing mechanism and shoe by a 'cam moving with the shoe and actlng to so vary the connections betweenthe feeler and the mechanism which relatively tips the sewing mechanism and shoe, that this mechanism efiects an additional tip without a corresponding change in the position of the feeler. j

In addition to the features of invention indicated above, the invention also includes certain further features of construction and combinations of parts which will be vhere-.

inafter described and setforth'in the claims. The various features of the invention will be readily understood from an inspection of the accompanying drawings and the fol lowing detailed description of the mechanism illustratedtherein. I a

Inthe drawings, Figure 1 is a side eleva tion showing so much of the automatic inseam sewing machine of the application above referred to as is necessary to illustrate the application of thevpresent invention thereto, Fig. 2 is a detail end View of the mechanism, for varying the connections between the controlling feeler and the mechanism for determining the angular. position of the sewing head; and Fig. 3 is a detail plan View of the parts shown in Fig. 2. a

In the -machine' shown in the drawings,

the. means for operating on the shoe consists of a sewing mechanism indicated at 2, which is similar in construction to the well-known Goodyear welt and turn sewing machine shown and described in Patent No. 412,704,

correcting mechanism such as shown in Pat- I ent No. 1,088,390, which is controlled by a feeler 6 acting along the channel approximately at the sewing point, as fully shown and described-in the application above referred to. The sewing mechanismis mounted on a support or head 8, which is automatically tipped both transversely and longitudinally of the feed during the sewing to vary the angular relation of the work and v sewing mechanism, and thusmaintain the sewing mechanism in proper relation to the I surface ofthe sole at the sewing point by correcting mechanisms which are controlled by feelers acting along the surface of the sole adjacent to the channeland approxi- 7 '7 mately at the sewing point. For the sake of simplicity, the same feeler 6 which controls the swinging movements ofthe jack is also utilized to control the longitudinal tipping movements of the support 8 for the sewing mechanism, the horizontal position of the:

end of the feeler determining the swing ing movement of the jack'and the vertical position of the end of the feeler determiningthe tipping movements of the head. The

transverse tipping of the head 8 is determined and controlled by the vertical position of a second feeler 10 which engages the surface of the shoe sole within. the channel. The vertical position of the'endof the feeler acts through mechanism, more fully shown and described in the above application and indicated generally at 12, to control a mechanism which determines the position of the head 8 on the segmental guideways 14, and consequently the lateral tip of the sewing mechanism with relation to the shoe sole.

The mechanism for moving and determining the position of the head 8 on the segmental guideways comprises a reciprocating'roll carriage 16 connectedby a-link 18 to a lever 20, which in turn is connected by a link 22 with the lower end of the lever 24, the upper end -of which bears against a sleeve 26 mounted to slide on the rotary carrier 28 on V which the ways 14 are formed. The sleeve is connectedwith the head 8 through a bar 30, bell crank lever 32,-and links 34 and 36,

as more fully described in Patent No. 1,082,185. The roll carriage is mounted to reciprocate on guide bars-38, and is provided with two pivoted roll carriers 40 in which are mounted rolls engaging a continuously rotating drum 42. The outer ends of the roll carriers are provided with'arms,

' the ends of which are connected by a link144 which is connected by a link'46 to the end of the lever 48, as more fully shown and described in the application above referred to. The other end of the lever 48 carries a roll engaging an annular groove 50 in the hub of a controller cam 52 mounted to rotate and slide longitudinally on a shaft 54 which makes one revolution for each cycle of the sewing mechanism. The position of the controller cam lengthwise of its shaft determinesthe position of the roller carriage 16 lengthwise of the drum 42, and the'position of the carriage in turn determines the lat eral -tip of the sewing mechanism. A change in the position of the controller cam will swing the lever 48', and thus turn the roll carriers 40 so that the rolls carried thereby will stand at an angle to the drum 42. When this occurs, the roll carriage will travel lengthwise of the drum until this travel restores the rolls to position with their axes parallel to the axis of the drum,

after which the rolls will rotate idly until they are again turned at an angle by another shift in the position of the controller cam. The movement of the roll carriage will, through the connections described, cause a change in the lateral tip of the sewing mechanism. The position of the controller cam, and consequently the lateral tip 7 of the sewing mechanism, is determined by a controller'roll56, which has a diameter substantially equal to the width of the central groove 58 of the controller cam, and

is so mounted that it may be moved into the path of one or the other of the inclined cam surfaces 60 which lead to the central groove.

groove of the controller cam at the time in f If the controller roll isin line with the central L the cycle of operations that the roll enters in the cycle of operations when it enters the groove in the controller cam, one of the cam surfaces 60willride against the roll, shifting the controller cam on its shaft and thus effecting a change in the lateral tip of the sewing mechanism. The position of the controller roll 56 during'each cycle of operations is controlled by the vertical position of the feeler 10 through the mechanism indicated at 12, which is connected with the roll through wires 62 and 64 having their ends connectedwith the bar 66 which carries the roll, and with a disk 68,.the position of which is determined during each cycle of the sewing mechanism by the vertical position of the end of the "feeler 10 when in engagement with the surface of the shoe sole,

Asthus far described, the machine corresponds 111 construction and mode of opera tion to the machine shown and described in the application above referred to. In addition to the mechanism for controlling the lateral tip of the sewing mechanism bythe feeler engaging the shoe'sole, the .machine thus be changed while operating along any predetermined part of the shoe, without interfering with the action of the feeler in effecting changes in the lateral tip indicated by changes in the contour ofthe sole along such portion, of the shoe. position of the controller roll to be changed without a corresponding change in the feeler or feeler mechanism, the end wires 62 and 64 are connected with the bar 66 by means of a rod 70 which passes through the bar and is so, connected therewith that the bar may be moved endwise. with re lation thereto. As shown, the rod is provided near one end with a screw thread 72 engaged by internal threads on a pinion 7 4 V which is held from, endwise movement within a slot? 6 in the bar.

The rod is held from rotation in the bar by a pin 78 passing through a slot 80 in the rod. By turning the pinion 74: the bar and controller roll 56 carried thereby may be shifted endwise to vary the lateral tip of the sewing mechanism'without changing the position of the rod 70. Any endwise movement of the rod 70, however, results in a corresponding movement of the bar and controller roll: The pinion 7 4: is engaged by a gear segment 82 secured to the end of a rockgsleeve 84- The rock sleevecarries a bell crank lever 86, one arm of which is connected with a spring 88 tending to move the gear segment in one direction, and the other arm of which rests upon one armfof a bell crank lever 90. The other arm of the bell crank lever 90 is connected by a link 92 to the arm of a second bell crank lever 94, the other arm of which is connected by a link 96 with the rear end of'the lever 98. The forward end of the lever 98 engages the upper surface of a cam plate 100 which is secured to the rotary head 102 through which the jack is rotated. The'cam plate is provided with a cam 104: which acts through the connections described to turn the pinion 74 to increase the lateral tip of the sewing mecha-v nism when sewing about the toe of the shoe. The cam plate may also be provided with cams 106 for turning the pinion 74 to in- 7 other operating mechanism.

To enable the crease the lateral tip of the sewing mechanism in sewing through theshank, should such additional tipbedesirable.

While the invention has been shownand' described as embodied in a mechanism for varying the relative lateraltip between a shoe and a sewing mechanism,it will be understood that'it is not confined in its application to such a'mechanism or machine, but may, if found'desirable, be embodiedin mechanismsfor otherwise varying the angularj relation of the. shoe and sewing or It will alsobe understood that the specific construction and arrangement of parts 1 shown and described is; not essential to the broader features of theinvention, and may be varied or modified-as found desirable or best suited to the construction. and arrangeone form of mechanism'in which it maybe embodied, what is claimed-is:.
